Application filed April 12,1910. Serial No. 555,026.

Patented Dec. 31,1912.

To all whom itmay concern:

Be it known that I, RUDOLF SCHNEIDER, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Closures for Tubes and the Like, of which the following is a specification. a

My present invention pertains to him provements in closures for tubes and the like, the construction and advantages of which will be hereinafter set forth, reference being bad to the annexeddrawings, wherein:

Figure 1 is a side elevation of a tube with the cap or closure applied thereto- .Fig. 2 a similar view, the upper portion ofthe tube and the ca being shown in section; Fig. 3 a sectiona elevation of the cap on a somewhat enlarged scale; and Fig. 4 a perspective viewof the cap-compressing spiral sprmg.-

The object of the present invention is to provide a simple and efiective closure for. the ends of tubes 'or the like, which is readily applied and as easily removed, the

structurebeing effective in use, both maintaining its position a ainst accidental displacement and also e ecting a tight fit and consequently aood joint with t e tube or bod it is used.

with whic ile more especially designed for use in connection with navigational sounding in practice spring brass wire or the like.

tubes, the constructionis capable of being employed with other structures, such as botties and the like.

In'the draw ng denotes a tube; 2 an enlarged rubber cap, the wall of which preferabl tapers toward its lower end, and V g s iraI formed of sprmg me e of several convolutions 0t 3 the bin oft The" inner diameter of the embracin coil or spiral is of substantially the same diameter as the outer diameter of thelower end.

ing no void or space which is not subjected to the compressive action of the spring.

e ta- By having the wall of the cap ma pering, the closure "may be employed with tubes of varying external diameters, for all that is necessary is to force the coil u wardly to a' slight extent, when it will brought to bear upon all the thicker sections e cap and t huglgmg or compressive action.

to the wall oi tight joint,

ereby caused to exert its aving thus described my invention,

what I claim is:

1. A closure, comprising a rubber cap and a coiled spring encircling the same, the coils lying in lanes substantially at right angles to the 'l dngitudinal axis ofthe cap. 2. A closure, comprising a rubber cap, the

outer wall of which is tapered, and a coiled spring encircling and embracin-g'saidwwall, one or more of the coils ofthe plet ely encircling the cap.

In testimony whereof I have signed my I "ecification in the presence" of two subscribmgwitnesses. v
